At least two people were killed when a freight train hauling coal derailed west of Baltimore late Monday.

Police and fire department personnel responded to an emergency call at about 11:45 p.m. Monday and reported that 21 of the train’s 80 cars flipped over and fell from a bridge in Ellicott City, Md, a city just 14 miles from Baltimore. The cars contained coal but were not carrying any hazardous materials.

The CSX train left from Grafton, W. Va., and was bound for Baltimore.

“Many of those train cars fell onto automobiles, literally fell onto automobiles with the coal, so you have massive piles of coal and heavy train cars on top of automobiles,” Howard County Executive Ken Ulman said.

The victims were identified Tuesday as Elizabeth Nass, 19, and Rose Mayr, 19, both of Ellicott City. Howard County police said the young women were sitting on the ledge of a bridge with their backs to the side of the passing train at the time of the derailment, but were not railroad employees; officers did not know why they were there.

Both Mayr and Nass both tweeted and posted pictures about sitting on the bridge around 9 p.m.

Their bodies were found buried under a pile of coal that spilled out from the open cars.
